Metoda Java Timer schedule().

Metoda rasporeda (zadatak TimerTask, datum vrijeme) klase Timer koristi se za planiranje izvršenja zadatka u zadano vrijeme. Ako je dano vrijeme u prošlosti, zadatak je zakazan u tom pokretu za izvršenje.

Sintaksa

 public void schedule(TimerTask task, Date time) 

Parametar

zadatak - to je zadatak koji treba rasporediti.

vrijeme - to je vrijeme u kojem se zadatak treba izvršiti.

Bacanja

IllegalArgumentException - Izbacuje iznimku kada je time.getTime() negativan.

IllegalStateException - Izbacuje iznimku kada je zadatak zakazan ili otkazan, ili kada je mjerač vremena otkazan, ili kada je nit mjerača vremena prekinuta.

NullPointerException - Izbacuje iznimku kada su zadatak ili vrijeme nulti.

Raspored (zadatak TimerTask, Date firstTime, dugo razdoblje) je metoda klase Timer. Koristi se za ponovno i ponovno planiranje zadanog zadatka u zadanom fiksnom vremenu izvršenja.

Sintaksa

 public void schedule(TimerTask task, Date firstTime, long period) 

Parametar

zadatak - To je zadatak koji je zakazan.

prvi put - To je prvi put u kojem se zadani zadatak izvršava.

razdoblje - To je vrijeme izvršenja u milisekundama.

Bacanja

IllegalArgumentException - Izbacuje iznimku kada je firstTime.getTime() manji od 0 ili je razdoblje veće ili jednako 0

IllegalStateException - Izbacuje iznimku kada je zadatak već zakazan ili otkazan, ili kada je mjerač vremena otkazan, ili kada je nit mjerača vremena prekinuta.

NullPointerException - Izbacuje iznimku kada su zadatak ili vrijeme nulti.
